ENVELOP.

Specification of Letters Patent.

Patented June 15, 1909.

Application filed April 10, 1909. Serial No. 489,085.

To all whom it may concern:

Be it known that 1, WILLIAM M. SMITH, a citizen of the United States,residing at Turtle Creek, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inEnvelope, of which the following is a specification. V

This invention relates to envelops and the object thereof is to providean envelop particularly adapted for second class postal matter, and sodesigned as to allow the postal authorities to thoroughly inspect thecontents of the envelop to ascertain whether it is second class postalmatter or not, without removing the same from the envelop. At

the same time the envelop is so constructed to prevent the removal ofthe contents thereof without destroying the envelop.

A further object of the invention is to provide an envelop for secondclass postal matter which embodies the advantages of an envelop used forfirst class postal matter, yet so designed as to fall within theprovince of an envelop possessing the necessary attributes to allow of aconvenient inspection of the contents without destroying the envelop andwithout removing or injuring the matter contained in the envelop.

Further objects of the invention are to provide an envelop for secondclasspostal matter which shall be simple in its construc' tion andarrangement, efficient in its use, convenient in use, and inexpensive tomanuiacture.

In describing the invention in detail, reference is had to theaccompanying drawings wherein is shown the preferred embodiment of theinvention, but it is to be understood that changes, variations andmodifications can be resorted to which come within the sco e of theclaims hereunto ap ended.

eferring to the drawings: igure 1 is a rear elevation of an envelop inaccordance with this invention. Fig. 2 1s alike view of a modified form,and,'Fig. 3 is a section on line XX of Fig. 2.

Referring to Fig. 1 of the drawings, 4 'denotes the body portion of anenvelop which is provided with a sealing flap 5 and also terminates in aback flap 6. T e body portion 1 has attached thereto the end flaps 7 and8. The sealing flap 5 is provided on its inner face with an adhesivesubstance as at 9 whereb the said sealin flap can be secured to the ackflap 6 and end flaps 7 and 8.

to the 3 of said opening. The

opening 10 of inverted pyramidal shape and which is closed through themedium of a flap 11, the upper end of the flap 1] being secured as at 12to the inner face of the back flap 5. The length of the flap 11 isslightly greater than the length of the opening 10 and the width of theflap 1 1 is materially greater than the width of the opening 10 so as toproject beyond each edge of said opening. The opening 10 is provided toallow the postal authorities to inspect the contents of the envelop toascertain whether it is second class matter .ornot. The flap 11 not onlyconstitutes a means to close the opening IO-but also conceals thecontents of'the envelop. The length of the opening 10 with respect tothe length of the envelop is such as to prevent the contents of theenvelop from being removed therefrom through the opening, the flap 11also constitutes a preventive for the removal of the contents of theenvelop.

Referring to Figs. 2 and 3 of the drawings, 13 denotes the body portionof the envelop, 14 the sealing flap, 15 the adhesive substance on thesealing flap, 16 and 17 the end flaps and 18 the back flap. In the formof envelo shown in Fig. 1 as well as that shown in Fig. 2 the back flapis connected to the end flaps and the sealing flap adapted to be securedto the end flaps and back flap.

The envelop as shown in Fig. 2 has the rear thereof provided with anopening 19 substantially rectangular in contour and with the lower edgeinclined outwardly from each end toward the-center as at 20. The opening19 extends longitudinally with respect to the envelop and is formed notonly in the back flap but also in the end flaps. However, the opening 19is of such length as not to .allow the removal of the contents of theenvelop through the said 0 ening. The opening 19 is closed through tl fmedium ofa flap 21 which has its upper portion as at 22 secured to theinner face of the back flap 18 and end flaps 16 and 17. The fia 21 is ofa length substantially equal l dngth of the opening 19, but is widerthan said opening 19 so that the flap 21 will project beyond the to andbottom edges notion of the opening 19 and flap 21 is the same as thatreferred to in connection with the opening 10 and flap'll.

It is evident from the foregoing construc-- tion ofenveloo that one .isset un which can matter which will enable the contents of the envelop tobe conveniently inspected by the ostal authorities, and which possessesall t e advantages of an envelop employed for first class postal.matter. 1

What I claim is:

1. An envelop having the rear thereof formed with an opening, and a flapSGUlI'fifl to the inner face of the rear of the envelop for closing saidopening.

2. An envelop having the rear thereof formed with an opening, and a flapsecured, to the inner face of the rear of the enveio for closing saidopening, said flap of a width greater than the width of the o ening soas to project beyond the upper and lower edges of-the opening.

3. An envelop having the rear thereof formed with an opening, and a flapsecured to the inner face of the rear of the envelop for closing saidopening, said flap of a width greater than the width of the opening soas to project beyond, the upper and lower edges 4. An envelop comprisinga body portion,
